Detailsinfo

A vulnerability was found in Norman Virus Control up to 5.82 (Anti-Malware Software) and classified as critical. This issue affects an unknown part. The manipulation of the argument string with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The nvcoaft51 driver in Norman Virus Control (NVC) 5.82 uses weak permissions (unrestricted write access) for the NvcOa device, which allows local users to gain privileges by (1) triggering a buffer overflow in a kernel pool via a string argument to ioctl 0xBF67201C; or by (2) sending a crafted KEVENT structure through ioctl 0xBF672028 to overwrite arbitrary memory locations.

The bug was discovered 08/30/2007. The weakness was published 08/31/2007 as not defined posting (Bugtraq). It is possible to read the advisory at securityfocus.com. The identification of this vulnerability is CVE-2007-4648 since 08/31/2007. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (36373), SecurityFocus (BID 25499†), OSVDB (45872†), SecurityTracker (ID 1018636†) and Vulnerability Center (SBV-16042†). Be aware that VulDB is the high quality source for vulnerability data.
